SECOND LAW OF THERMODYNAMICS ThermodynamicsSummaryThe important information from this chapter is summarized below.Second Law of Thermodynamics Summary Plancks statement of the Second Law of Thermodynamics is:It is impossible to construct an engine that will work in acomplete cycle and produce no other effect except the raising ofa weight and the cooling of a heat reservoir. The Second Law of Thermodynamics demonstrates that the maximum possibleefficiency of a system is the Carnot efficiency written as:h = (TH - TC)/TH The maximum efficiency of a closed cycle can be determined by calculating theefficiency of a Carnot cycle operating between the same value of high and lowtemperatures. The efficiency of a component can be calculated by comparing the workproduced by the component to the work that would have been produced by anideal component operating isentropically between the same inlet and outletconditions. An isentropic expansion or compression process will be represented as a verticalline on a T-s or h-s diagram. A real expansion or compression process will looksimilar, but will be slanted slightly to the right. Efficiency will be decreased by:Presence of frictionHeat lossesCycle inefficienciesHT-01 Page 96 Rev. 0
